A simple, rapid, accurate method for determining calcium and magnesium separately in 0.1 ml. volumes of serum (or heparinized plasma) was required for the routine chemical pathology service of a children's hospital (Wilkinson, 1955-6). The apparatus used had to be generally available, the minimum of pipetting and transfer was desirable for the sake of accuracy, and the method had to be specific...

This study explored the effect of activated carbon preparation conditions on their adsorption performance. Activated prepared from Wood chips Prosopis juliflora has been utilized as adsorbent for removal Eriochrome Black T an aqueous solution. was used source material to prepare by pyrolysis process using H3PO4 activation. The properties were evaluated IDOINE NUMBER. effects various impregnatio...

The current study focused on utilizing cobalt oxide to eliminate hazardous Eriochrome Black T (EBT) dye. impact of pH (2, 4, 7, 8, and 10) temperature (45, 50, 55 °C) was examined for EBT removal. results show that the maximum sorption occurred at = 2 removal percentage increased with increasing temperature. Five non-linear regression methods were used predict best isotherm kinetic models. A co...
